    hey people, new on here and looking for some help

    i have a quad with a 200cc liquid cooled zongshen/cg200 engine. the problem is it has got a very bad rattle, it's really loud and i cant figure out what it is.

    i have recorded a audio file of the noise, its a very high pitched sound and you cant really hear the exhaust, it overpowers it, it almost sounds like somethings loose

    here it is http://www.zshare.net/audio/82492990bfd056f4/

    hey people

    i have had another look at the quad, i have found the exhaust is leaker at the barrel, a bolt has been snapped inside the thread (i can re-tap it).

    i took the spark plug our and turned the engine over by electric start, i cant hear any noise from the engine, so im wondering if this rattle is coming from the exhaust joint? you can wobble the exhaust so maybe this is causing vibration and valve/combustion noise?
